richard...
in your example, wouldn't app A, essentially download the code from app B,
and run the source on app A? or would the code be run on app B, with the
resulting html/content/page being transferred to app A?
would this be better if it were perhaps done as a soap client/server
process... of course, the fact that the user's php would have to have the
soap extensions installed would be an issue...

The trick, then, is for app B to make its SOURCE CODE available for
curl on server A to snatch.
http://b.example.com/source_code.php?filename=login.php
<?php
//really BAD INSECURE code for illustration:
$filename = $_GET['filename'];
header("Content-type: text/plain");
readfile($filename);
?>
On server A:
<?php
include "http://b.example.com/source_code.php?filename=login.php";;
?>
Or you could use curl to get the code and eval it, or you could use
file_get_contents and eval it, or you could get the code, save it to a
temp file, and then include the temp file, or you could...
It's not that it can't be done. It's that there are so many ways to
do it, we don't know where to start.

If the PHP file has a .php extension, it will be run on the webserver
like any PHP page. If it is .txt or you set Apache directives, etc.,
it will be transferred to the client app.

ok...
so can i do something like...
+-------------------------------+
| |
| user |
| 'sub_btn' |
| |
| |
| |
| |
| blah |
| blah |
| blah |
| |
| |
| |
+-------------------------------+
in this example, the user/sub_btn is generated from the app B server/system.
the user would then fill in the 'user' and hit the 'sub_btn', causing the
information to be sent back to the app B server.
the app B server would then return a result, based on the user input... i'm
trying to figure out how to essentially allocate a section of the page, to a
remote application. after i've finished with the remote stuff, the user
could go ahead and select other items/buttons on the page that are in the
current environment
+-------------------------------+
| |
| +-------------+ |
| | remote | |
| | app | |
| | area | |
| +-------------+ |
| |
| |
| local app space.... |
| |
| blah |
| blah |
| blah |
| |
| |
| |
+-------------------------------+
i'm not sure what's the best approach to this...
thanks

You could just use an iframe...

which also has a link to the PHP bug report in the thread. Not sure if
this
is relevant to PHP5, but thought I'd mention that something similar
exist(ed?) in the 4.4.1 version.
There is also a bug report which is now closed for my problem !! This
bug still exists in the latest PHP 5.1 in snaps.php.net. Mind you my
apache is a fink binary, not bsd ports. There is huge issues compiling
apache under osx bsd, hence why i had to go with the binary. Mind you
osx is my dev environment coz its also my laptop,it is not production
lol, our production machine however is also BSD. To prove it wasnt thee
rewrite rule, i made it [L] to a standard html file and it was fine, so
there is something up with it in php obviouslly in the module.

Of course i dont get what your trying to do, the rewriterule

Also You mention fink but then you mention bsd, does it happen on
both systems?
As far it trying to download the faked url, what exactly is it
trying to download and what are the headers for the request as
well.
The hanging could be a loop of some sort, have you looked at the
output of the rewrite log to see exactly what is going on?

Its a prefork setup, worker would be nice though :D

Errm live system is running php 4.4.1 / Apache 1.3 and its ok. Im
looking at upgrading it to php 5.1 when its out.

Could you come up with a simplified example that causes the error,
so it could be tested on other systems. I was able to have
something like:
RewriteRule ^(.*)/(.*)/$ /index.php?f=$1&b=$2 [L]
And accessing /foo/bar/ It worked like a charm with:
$_GET['f'] == '/foo' and $_GET['b'] == 'bar'
When I used the ../../index.php it would cause a 400 Bad Request,
i'm not clear on how your are doing your relative paths.

yeah, this makes me wonder if there are issues with the fink binary
you are using. Is the web server going to get upgraded to 2.x as
well? I know that php has a completely different way to talk with
the 1.x vs 2.x which can complicate the issue a bit.

You can set:
RewriteLog /path/to/writable/file
RewriteLogLevel 9 #where 9 is the most verbose

I'm not really sure what this means, it is related to the
./configure options for apache --enable-optional-hook*, i have no
clue what that does.

I should think all those .* should be .+ instead...
I mean, if somebody surfs to this URL:
http://example.com//////example.video
There's nothing really wrong with a URL like that, and I used to do
the same thing until I discovered another fly in this particular
ointment. Should source URLs like these ever appear in Microsoft
Outlook, they are likely to get 'corrected', for example a URL that
goes in as:
http://example.com//////example.video
When you click it, you're quite likely to have it go to:
http://example.com/example.video
thus completely missing all your mod_rewrite patterns. This is why we
love MS so. I've taken up using _ as a pattern separator as a
workaround.
There's also a very nasty bug in current mod_rewrite (at least in
Apache 2.0.54) where mod_rewrite url decodes submatches between input
and output URLs, so for example:
RewriteRule ^(.*) blah.php?x$1
if you feed that a URL that contains a URL encoded value like 'Hello%
20there', your resulting URL will be: 'blah.php?x=Hello there', which
is obviously broken.

yeah, the final result would need to look like that. Without an
example i would guess the question would be more how do i get my
statement to send NULL instead of ''.
<?php
$sql_quoted = array(); // shiflett' -- style
$myFieldValue = isset($POST['myFieldValue'])? $_POST['myFieldValue']: '';
if (strlen(trim($myFieldValue)) {
$sql_quoted['myField'] = "'" . mysql_real_escape_string($myFieldValue) . "'";
} else {
$sql_quoted['myField'] = 'NULL';
}
$query = "INSERT INTO myTable(myField) VALUES({$sql_quoted['myField']})";
echo $query;
?>
And if the field posted was empty, it will be indentical to
Jasper's sql, other wise it will be a properly quoted string.

Php experts everywhere,
I want to merge two arrays, and I want to store the result as the first
array. Something like the following:
$array1 = array_merge ($array1, $array2);
So far the code gives me what I want. However, suppose if $array1 is
extremely huge, am I introducing a bug here because of possible race
condition? It's possible that array_merge has two write something to
$array1 (left hand side) before it even finishes reading it (argument)
in the first place. Let alone merging the two.
Should I just go conservative and do:
$tmp = array_merge($array1, $array2);
$array1 = $tmp;
Thank you,
Ezra

Hello,
What is the future of the xml-rpc client and server functions in php
5.x? I see the old xml-rpc extension is still marked as expirimental
and the newer xml-rpci extention in pecl has not been worked on in 8
months and doesn't have server functionality. I am in the process of
porting a large web app to php and I want to use the most updated and
maintained xml-rpc implimentation.
Thanks,

hello,
I was wondering, is there a way to get a connection's name(host's name
instead of just ip),
i am using the cli version of php and am now using the function
getpeername() but for example, i would like to be able to have it say
something like "connection: localhost ...." instead of "connection:
127.0.0.1"
is this possible with the command line interface?
I am using php 4.3.10 on linux

I assume you really mean socket_getpeername().
You just have to do a reverse lookup using gethostbyaddr(), pending
your host and named settings you will get back either localhost or
the hostname you have (hopefully it is localhost), if it can't be
resolved it will be the IP.
if it is the IP instead of a localhost/hostname you'll have to fix
your systems configuration.

Hi All,
I have a server process that sends fax,print, etc (both in C# and in Java).
Currently it polls says the fax table in the database for any fax jobs.
How can I get my PHP script to call or notify these services directly so not
having to wait for the next poll.
I can't open a socket to the server vai the PHP so what mechanism do I use?
Any hints will be grateful

It just sounds like you have cookies disabled or not allowed for this
